SPECIFIGA TION forming part of Iletters Patent No. 747,939, datedDecember 29, 1903.

Original application filed May 20, 1901, gerial No. 61.124. Divided andthis application filed June 24, 1901. Serial No- 65850. (No model.)

Be it known that LEDWARD THOMAS CLEA- THERO, of The Hollies, Barringtonroad, Altrincham, in the county of Chester, England, have inventedcertain new and useful Improvements in Platen-Presses such as are Usedfor Printing, Stamping, or the Like; and I do hereby declare thefollowing to baa full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention is a division from my application, Serial No; 61,124,filed May 20, 190 1, relates to platen-presses such as are used forprinting, stamping, and the like, and will be best understood byreference to the accompanying drawings, in which.

Figure 1 is a front elevation of one of the Figs. 2 and 3 are elevationsof respectively the right and left hand Fig. 4 is arear elevation. Fig.5is a front elevation, and Fig. 6 an elevation of the right-hand side ofFig. 5, of a portion of the press, showing the platenoperating mechanismand devices for secur-' i-ng double inking of a heavy form. Fig. 7 is afront elevation of the platen. Fig. 8 is an elevation of the left-handend of Fig. 7. Fig. 8 is a sectional'elevation of a part of Fig. 8,showing the grippers open. Fig. 9 is a rear elevation of the type or diebed and its Fig. 10 is a vertical section on the crooked line 10 10 ofFig. 9. Fig. 11 is a plan of Fig. 9. elevation of the feed and deliverycarriage and its operating mechanism, and Fig.- 13 is avertical sectionon the crooked line 13 13 of Fig. 12.

The detail drawings shown in Figs. to 13, inclusive, are represented ona scale larger than that to which the others figures are drawn.

Throughout the several figures of the drawings similar numerals ofreference are used to indicate similar parts of the press.

In constructing a press according to this invention twoside frames 1 and2 are provided, having bearings for carrying the variousoperating-shafts. The short shaft 3 is that which is first operated fromany suitable Fig. 12 is a frontoutside source of rotary motion throughthe medium of a fast pulley l (5 representing the loose pulley) orotherwise, as may be desired. The said shaft is supported at one end ina bearing in the side frame land at the opposite or outer end in aplumber-block bearing 6 and has secured on it a spur-pinion 7, gearingwith a wheel 8, rotating on a stud 9, secured in the side frame 1. Thespur-wheel 8 gears with a wheel of half its diameter, secured on one endof a crank-shaft 11, rotating in bearings 12, extending inward from theside frames 1 and 2 and supported on a bed 13.

The crank 14: at or near the center of the shaft 11 engages withthelower end of a connecting-link 15, whereof the upper end is pivoted on ashaft 16 whose ends eccentric in relation to the central part 16 andconcentric with each other are journaled in lugs On the right-hand endof the crank-shaft 11 is secured a disk 21, carrying a crank-pin 22,pivoted to the lower end ofa rod 23, at.

the upper end of which is formed a. toothed rack 24, which is held inengagement with a spur-wheel by a guide-roller 26, pivoted on the sideframe 1. The spur-wheel 25 is mounted loosely on one end of'theplatenshaft 27, being retained thereon by a nut and washer 28, as shownclearly in Figs. 5 and 6. v

The spur-wheel 25 is or may be formed inte-' gral with a disk or plate29, provided at its inner side with guides 30, in which a tooth or pawl31 is capable of sliding radiallyiu relation to the axis of the shaft27. 9n the tooth 31 is pivoted an antifriction-roller 32, adapted whentheplate 29 is oscillated by te rack 2 1 and spur-wheel 25 to besuccessively; engaged'by two cams 33 and 34, hereinafter moreparticularly described. 7

35 is adisk rigidly secured'on the platenshaft 27 between the outer sideof the frame land the oscillating plate 29. This disk is provided withtwo diametrically opposite reeesses 36, with which, as hereinafter morefully described, the tooth or pawl 31 is engaged for rotating theplatens and from which it is released when during the continuedoscillation of the toothed wheel 25 and plate 29 the platen is to remainat rest.

The before-mentioned cam 33 is pivoted at 37 to the side frame 1 and isprovided with an arm 38, against which a plunger or red 39 is pressed bya spring 40, abutting against a lug 41, projecting from the frame 1, thetendency of the said spring being always to raise the cam 33 into theposition in which it is shown in full lines in Fig. 6. The cam 34 isrigidly secured to the side frame 1 above the axis of the platen-shaft27 and raises the tooth 31 out of engagement from the recesses 36 whenthe antifriction-roller 32 is moved along the said cam. When the toothedrack 24 is in its lowest position, the tooth 31 is at the upper end ofits stroke and held out of engagement from the then upper recess 36 bythe fixed cam 34. During the ascent of the rack 24 the tooth or pawl 31travels downward free of the disk 35, the roller 32 passing first overthe fixed cam 34 and then over the pivoted cam 33, the latter beingpressed downward against the influence of the spring 40 by reason of theinner end of the tooth 31 traveling upon the periphery of the disk 35.When the tooth 31 reaches the then lower recess 36, it is immediatelypressed thereinto by the spring 40 acting through the cam 33 on theroller 32, so that during the next ensuing descent of lhe rack 24 thespur-wheel 25 is locked to and rotated (through half a revolution) as ifin one piece with the platenshaft 27.

The platen-shaft 27 has secured on it a platen-frame 42, having twodiametrically opposite platens 43 44 and carrying two shafts 45, eachprovided with two arms 46, in which is journaled a shaft 47, whereon areadjustably secured any desired number of grippers 48, serving to gripthe material to be printed or stamped against or upon the adjacent edgeof the platen 43 or 44. One end of each of the shafts 45 projectsoutwardly through the platen-frame 42 and has secured on it an arm 49,carrying an antifriction-roller 50, adapted to be engaged by a cam 51,formed on the upper end of a lever 52, pivoted at 53 to the adjacentside frame 2. The lower end of the cam-lever 52 is provided with acam-slot 54, within which works an arm or projection 55, extending fromthe vertically-reciprocating type or die bed 18, the said arm during itsascent causing the cam 51 to move forward (from a position in whichitisoutof the path of the rollers to beneath, and thereby raise the thenuppermost of the rollers 50 to open the grippers and for a given timemaintain the said grippers open. During the first part of the descent ofthe arm or projection it still keeps the cam 51 forward under the roller50, and during the latter part thereof it withdraws the cam from thepath of the roller 50 and allows the grippers 48 to close.

Each of the grippershafts 47 has secured on it a lever 56, whereof oneend is connected to a spring 57, attached to the platen-frame 42, andthe other end is provided with an antifriction-roller 58, which, by thesaid spring,

'is constantly held in contact with a lug or projection 59, formed on orrigidly secured to the platen-frame 42. By this arrangement the springs57, while tending always to keep the grippers 48 closed, allow them tobe opened by the forward tilting of the lever 52, as shown in Fig. 8,and to be closed when the lever 52 is tilted rearward.

At the upper part of the side frames 1 and 2 inclined guides are formedfor receiving rollers 61, pivoted on the end plates 62 of the feed anddelivery carriage 63. In the end plates 62 are mounted fourgripper-shafts 64, 65, 66, and 67, of which the two former carry thefeed-grippers 68 and 69, respectively, and the two latter carry thedelivery-grippers 70 and 71, respectively. The shafts and 67 are rigidlysecured in the end plates 62 and serve as tie-rods to secure therigidity of the feed and delivery carriage. On the righthand end of eachof the shafts 64 and 66 is secured an arm 72, on which is pivoted anantifriction-roller 73, adapted to engage with cams 74 and 75 and a hump75 ona rod 76, guided near its front end by a slot 77 in the said rod,working on a pin 78, fixed to the adjacent side frame 2. The shafts 64and 66 are provided with springs 79 and 80, Fig. 12, respectively, whichtend always to force the movable grippers 68 and toward the relativelyfixed grippers 69 and 71.

Near its rear end the camrod 76 is connected to one arm of a bell-cranklever 81, pivoted at 82 to the side frame 2, and of which the other armis pivoted to the upper end of a rod 83, reciprocated vertically in afixed guide 84 by a cam 85, secured on the beforedescribed crank-shaft11.

The feed and delivery carriage 63 is reciprocated in the guides 60 bymeans of the following mechanism, comprising two links 86, which atrespectively opposite ends are pivoted to the carriage end plates 62 andto two lever-arms 87, the latter secured on a rocking-shaft 88,supported in bearings 89 in the main side frames 1 and 2, the said shaftbeing rocked through the medium of a leverarm 90, forked rod 91, andantifriction-roller 92 by a cam-groove 93, formed in a disk 94, securedon the crank-shaft 11.

To retain the platen-frame 42 in proper position-i. e., with the twoplatens 43 44 h0rizontal-during the printing or stamping operation,there is provided the following looking mechanism, comprising tworigidly-connected locking-arms 95, adapted to engage with lugs or steps96, projecting from the left-hand end of the platen-frame 42, the saidarms being pivoted between fixed lugs 97 on the adjacent side frame 2and rocked into and out of the path of the lugs or stops 96 by means ofa lever-arm 98, which may, as

shown in the drawings, pass through a slot in the frame 2 and beintegral with the locking-arms, jointed links 99, alever 1'00, and a cam101, formed on the periphery of the before-described disk 94. A springis provided to maintain the lever 100 in operativ connection with thecam 101.

Theinking mechanism comprises a carriage 102, having rollers 103,whichrun in' horizontal guides 104, formed at the inner sides of themain frames land 2. To the ink ing-carriage 102 are connected two links105,

pivotedto two lever-arms 106, secured to a rocking shaft 107, supportedin hearings in the main frames 1 and 2, the said shaft being providedwith a third lever-arm 108, which through a link 109 and lover 110 isoscillated by a cam 111, formed in the before-described cam-disk 94. Theinkingcarriage 102 is formed with open bearings or vertical guides 112,in which the spindles of the two compo inking-rollers 113 and theintermediate riding-roller 114 are free to rotate and ascend anddescend. The spindles of the compo inking-rollers 113 are provided withthe usual metal rollers, which during the reciprocation of theinking-carriage 102 travel successively over track-rails 115 116, ofwhich the former are rigidly secured to the two sideedges of the type ordie bed 18, and the latter at their rearward ends are pivoted to thetrack-rails.

justed by set-screws 127 to regulate the supply of ink carried out ofthe trough 126 on the surface of the doctor-roller 125. Threedistributing-rollers 128 128 and 129 rotate in contact withtheiuking-drum 119 and the ink is transferred from the ductor-roller tothe distributing-roller 129 by a swingingductorroller 130, which iscaused to oscillate between the two said rollers and'for periods of thedesired duration remain in contact therewith by any of the well-knownand hitherto 'used arrangements of cam mechanism, which it has not beenconsidered necessary to represent in the drawings.

To throwoff an impression or,in other words, to prevent an impression ona platen-blanket when there is no blank sheet fed to it, the followingmechanism (illustrated most clearly in Figs. 9, 10, and 11) is provided:On the lefthand end of the before-described shaft 16 16 is secured aspur-pinion 131, in gear with a,

toothed sect-orl32, pivoted at 133 to the type or die bed 18 and havinga forwardly-projecting lever-arm 134, on which is pivoted anantifriction-roller 135. This roller isadapted to engage with astationary arm or bracket to be engaged by a pawl or hook 137, pivotedat 138 to the main frame and having a counterweight or weighted arm 139,which constantly tends to move the pawl or hook 137 i into ormaintain'it in the path of the roller as the latter is raised andlowered during the vertical reciprocation of the type or die Pivoted tothe counterweight 18 is a bed 18. swivel-eye 140,through which passesthe lower end of a rod 141, having a shoulder 142 to bear on the eye140, and thereby move the pawl or hook over the roller.135, the shoulderbeing held down onto the eye 140 by a compressionspring 143, whichexerts its pressure between the under side of the eye 140 and the nuts144, adjustable on the rod 141. The upper end of the rod 141 is pivotedon a crank-pin 145, carried by a short shaft 146, on the end of which,projecting at the outside of the main frame 2, is secured a crank-handle147.

In'the normal condition of working of the press the-crank-handle 147 ishorizontal, and

the pawl'or hook 137 extends into the path of the roller 135, so that ateach ascent of the type or die bed 18 by the arrestment of the roller135and the movement'ofthe fulcrum 133 in relation to said roller thetoothed sector 132 is rocked on 133 and the shaft 16 16 is turned in thedirection indicated by the arrow in Fig. 10, so that by virtue of therelative eccentricity of the shaft portions 16 16 the bed 18 is raisedin relation to the connecting-link 15 and the type or die 18*, Fig.

'9, carried on the'bed18,is caused to make the desired impression. Ateach descent of the bed 18 the roller 135 abuts against the fixed arm orbracke't'136, whereby through the sector 132 the shaft 16 16 is turnedin the direction opposite to that indicated by the arrow, whereby thebed 18 is lowered in relation to the connecting-link 15.

When the attendant fails to supply a blank sheet to the platens, andconsequently re-' sheet or blank will receive two successivesuperimposed impressions, this result being obtained by the followingmechanism. 148 is a cam, which, as shownin Figs. 2, 5, and 6, mayconveniently be formed in the-beforedes cribed spur-wheel 8 and engageswith an antifriction-roller 149, pivoted on a hand-lever 150, whoselower end is forked and straddles the boss of the wheel 8 or the stud 9.The hand-lever 150 at its upper end passes through a loop-guide 151, andit is capable of &

being moved into either of the two positions in which it is shown inrespectively full and dotted lines in Fig. 6, a pin 152 inserted in ahole in the side frame 1 or any other suitable device being provided forretaining the said lever in such positions, while allowing it to bereciprocated vertically by the cam 148. The hand-lever 150 is providedwith a hook 153, which when the said lever is in the dotted-lineposition of Fig. 6 engages a stud or projection 154 on thebefore-described cam 33.

For ordinary single inking of the form the hand-lever 150 is secured inthe full-line position of Fig. 6, and the cam 33 consequently causes thetooth 31 to engage with one of the recesses 36 at each oscillation ofthe plate 29. When, however, double inkingof the form is required, thehand-lever 150 is secured in the dotted-line position, so that atalternate rotations of the crank-shaft 11 (the spur-wheel 8 being twicethe diameter of the pinion 10) the cam 13 is drawn downward by the cam148, lever 150, hook 153, and stud 154, and thereforeis prevented frompressing the tooth 31 into engagement with the then lowermost recess 36,so that the next ensuing upward movement of the said tooth will have noeffect on the notched disk 35.

In the operation of the before-described press the attendant moves eachblank over the feed'board 155 until its rear edge projects slightly overthe rear edge of the said board, so that at the next forward movement ofthe feed and delivery carriage 63 the feed-grippers 68 and 69 of saidcarriage will be able to seize the said blank. The platen'frame 42 beingthen looked in position with the platens 43 44 horizontal, the carriage63 is moved forward, and when the feed-grippers 68 69 thereof are nearthe blank the cam-rod 76 is moved rearward and the cam 74 raises thegrippers 68 to allow the blank to enter between 68 and 69, the cam-rod76 being immediately thereafter moved forward to enable the grippers 68(under the influence of the spring 79) to close upon the blank,which isthereby firmly gripped between 68 and 69. The carriage 63 then makes itsrearward movement, and when the feed-grippers 68 69 are nearly over thethen open flattened grippers 48 the roller 73, appertaining to thefeedgrippers 68, strikes upon the cam-hump 75 and causes the saidgrippers to open and release the blank, which thereupon falls onto thethen uppermost platen, whereon it is immediately thereafter secured bythe closing of the appropriate platen-grippers 48. The carriage 63 thenreaches its rearmost position, and the platen-frame 42 is unlocked andcommences its semirotation, the carriage 63 remaining stationary untilthe platen is again brought to rest and locked with the blank inimpressing position. At this juncture the type or die bed 18 commencesto ascend, and the inking-carriage 102 commences to move forward, theinking-rollers 113 making one complete forward and backward movementover the type during each ascent of the bed 18, the inking-carriage 102remaining inoperative in its rearmost position during each descent ofthe bed 18.

Provided that, as before explained, the crank-handle 147 occupies itshorizontal position theblankreceivesitsimpressionatthe end of the upwardstroke of the bed 18, and when the latter descends the platen-fran1e 42makes its next semirotation, bringing a blank into impressing positionand the impressed sheet into delivery position, the platen-frame beingagain locked at the end of said semirotative movement. The feed anddelivery carriage 63 then makes its forward movement, and when near itsforemost position the cam-rod 76 is moved upward and rearward, so as toact on the rollers 73, and thereby raise the gripper-jaws 68 and 70, theformer for admitting a fresh blank and the latter for admitting theimpressed blank, the camrod 76 afterward being moved forward anddownward to allow of the said blank being gripped by the respectivegrippers 68 69 and 71. The carriage 63 is then moved backward, bringingthe fresh blank onto the then uppermost platen, as before explained, andcarrying the impressed blank over the delivery-board 156, a stationarycam or projection 157, Figs. 3 and 13, at this juncture serving toeffect the release of the said impressed blank by moving upward theroller 73, appertaining to the delivery gripper 70, as

shown in Fig. 3, when the latter is moved up to it.
